IMPROVED MILK-STRAINER.

@te tlgtbule referat 1t iu tiges tttcts rteut mit mating gint nf the smut TO ALL WHOM IT MAY' CONGERN:

Be it known that we, SINEYVAN AUunN and JAMES H. GRAiIAM, of Binghamton, in the; county of Broome, and State of New York, have invented a new and improved Apparatus for straining-Milk; and we do hereby declare that the following isa full and exact description -thereof', reference beingr had tothe accompanying drawings, making a part of this specification', in whicho Figure 1 is a perspective viewfot' our improvement, representing it as ready to he attached to the pail. Figure 2 is anV inverted View, showing the manner of securing it to 'the pail. i Figure 3 represents the wire strainer, one of the cams and the spring that holds the strainer in its place detached from their positions. y

Like letters of reference indicate like parts.

The nature of our invention consists in the employment of a detachable milk-strainer frame so constructed that it can be readily and securely.attachedto and vdetached from the peil, together with the arrangement for securing the strainer in the mouth of the cover bymeans of a detachable spring fitted to hold it in position, so that it may be removed and cleansed or replaced by another without soldering.

To enable others to malte and use our invention, weA will describe its construction and operation.

We make the frame A of malleable cast iron, or other suitable metallic substance,and of' a semieircular form, near the edge ot' which we cut a groove, B, for the purpose of inserting a stripof India rubber, C, which we place 'in it for the purpose of preventing leakage at the connections around the rim of the pail. The frame A is secured to the rim of the pail by means of two groovedcams D D, with handles, which work on apin projecting through from the outside of said rim, and placed low enough to receive the rim of the pail between the rubber C and the diminished part of the cams. In the mouth E of the cover F weV place the strainer G,Wl1ich is cutthe proper form and size. We then place it in the lower part'of said mouth, Where it rests upon an inside lflange, and is held in its position by.the4 spring H, which is bent to the proper form, so that it may be sprung in and removed by pressingr the two ends I I together.

When we use our invention wesielect the proper size for the pail, place it uponthe rim, then turn 'dovrn the cams D D, which secures it from leaking by the pressure of the rim of the pail against the rubber C. It is then ready for use. When necessary to cleanse the pail, the strainer-frame is removed by simply turning down the cams, and if the Wire strainer Gr in the mouth of the cover should become foul it is conveniently cleansed by removing it, which is accomplished by pressing the two ends I I of the spring together and slipping it out with the fingers. The ordinary mode of securing the wire strainer Gr in its place is by soldering, making it more dilicult to cleanse, and when necessary toreplacc it it can only be done at the shop, which, under some circumstances, would be quite inconvenient.

lWe are aware that there are in use strainers that are attached to the pail by other appliances than by. soldering, but they are dilerent in construction from our improvement, being more expensive and not as easily kept in the proper condition for use. We therefore disclaim any interference With'sucli, and confine ourselves only to the novel features of our invention,

Having thus described our invention, what we claim, and desire to secure by Letters Patent, isl The frame A and the mode of attaching it to the pail, in combination with the detachable `strainer Gr and the spring H, all constructed substantially as herein describedandrepresented for the purpose set forth SIDNEY VAN AUKEN.- JAMES H. GRAHAM.
